Multipurpose controlled three-phase inverter for motor driving and grid power injection applications

This paper reports the development of a control system for a three-phase power stage for an induction motor as well as for an RLC load, able to synchronize with a virtual grid. Vector current control strategy has been applied in both cases, although Volts-Hertz control method is also available in the case of driving the motor. The project includes the implementation of a control software in a DSP board as well as the development of a PCB that interfaces the inverter with such a platform. Several experimental results for both applications will be presented.
